In this survey study of US adults from 2000 to 2018, sexual inactivity increased among men aged 18 to 24 years and 25 to 34 years and women aged 25 to 34 years during the study period, with the increase among men mainly occurring among unmarried individuals. Men with lower income and with part-time or no employment were more likely to be sexually inactive, as were men and women who were students.
People who have fewer entertainment options have more sex. (I've seen it said that e.g. people living on small islands have lots of sex, which is part of how they remain populated even with so many people leaving). That doesn't mean that they're sexier - having lots of sex because you're bored is no more sexy than watching lots of porn. (You can look at swinger groups for the extreme example - they have a lot of sex but are profoundly unsexy to most people).
While these trends exist, they don't directly correlate with the invention of the smart phone or the behaviors the poster is stating are unsexy. It has more to do with social education, reduction of religion, and many other factors not discussed in their post.
These are just two results from a 30 second Google search. There is a ton of information out there that directly correlates both social media and immediate, ubiquitous access to it (i.e. smartphones) with negative social outcomes, including suicide rates.
Honestly "smartphone bad" is such a popular thing to publish and claim, and so directly contradictory to my own experience, that I don't credit it. It's like the D&D satanism panics or something.
Yes. Look at surveys of sexual activity. Not everyone would be more sexually successful, but the average would be different.
